According to the evidence-relative view of liability to defensive harm, a person is so liable if and only if she acts in a way that provides sufficient evidence to justify a (putative) victim’s belief that the person poses a threat of unjust harm, which may or may not be the case. Bas van der Vossen defends this position by analyzing, in relation to a version of Frank Jackson’s famous drug example, a case in which a putative murderer is killed by a putative victim. Van der Vossen submits that the putative murderer is liable to be killed, which is a verdict that can be accommodated only by the evidence-relative view. We argue that Van der Vossen’s attempt to ground the evidence-relative view of liability to defensive harm fails. We also argue that this notion should be construed in fact-relative terms. This, however, does not mean that the notion of permissibility should necessarily also be understood in such a way in all possible cases. So, we explore whether the evidence-relative view of permissibility may be used in some contexts.
